Title: Percussion fuses for projectiles
IPC: F42C15/26
Filed: 1919-12-23
Abstract: 137,282. Guerritore, O., (Assignee of Peynetti, P.). Dec. 31, 1918, [Convention date]. Projectile fuses.-Relates to percussion fuses of the kind in which the striker 9is held at safe until the projectile is in flight by centrifugal members, and consists in making these members in the fom of thick segments 15 with thin inner edges for locking the striker 9, whereby on impact, the striker can shear these edges and fire the fuse if the members have failed to move out of the safe position. As shown, the fuse comprises a momentum pellet 3 in addition to the direct action striker 9. The pellet and the striker are held apart by two springs 13, 10 both acting on the striker, but one taking its bearing against the pellet 3 and the other against a fixed screw-plug 11. The pellet and the striker are prevented from approaching each other by the pivoted segments 15, 15<1> which are urged inwards by springs 17. During flight, centrifugal force causes these segments to swing out, and they are looked against return by a projection 7 on a ring 5 which is thrust forward by a spring 6 after a temporary set back during the period of acceleration. During the same period, the outward swing of the segments 15, 15<1> is delayed by the frictional grip to which they are subjected by pressure from the striker 9 owing to its inertia. The striker 9 may be provided with a detachable extension 1.2, the length of which determines the actual instant of the explosion.

Title: Improvements in or relating to fire-extinguishing sprinkler systems and more particularly to automatic alarm apparatus therefor
IPC: A62C35/60
Filed: 1928-11-06
Abstract: 318,049. White, A. E., (Automatic Sprinkler Co. of America). Nov. 6, 1928. Alarms operated by flowing liquid.-In an alarm arrangement for automatic sprinkler systems, the flow of water to the alarm mechanism is controlled by a pilot valve adjustable so that false alarms due to water-hammer are prevented. and a fluid-pressurerespansive retarding device is also associated with the alarm mechanism. In the dry pipe system shown, the main water valve 18 is adjustably carried by an arm 21 which is loosely pivoted in the casing 16 at 25 in bearings having enlarged bores, the position of the pivot pin within the bores being controlled by a spring 31, so as to prevent lost motion at the pivot. A pilot valve 34, co-operating with a tubular seat member 37 which admits water to the alarm mechanism when the valve 18 opens, is so carried at the free end of the arm 21 that the latter can lift slightly, under water-hammer or the like, without lifting the valve 34, the extent of this free motion being adjustable by removing a plug and adjusting the member 37. An opening 48 in the casing 16 gives access to the pilot valve, and a pipe 47 conveying water to the alarm mechanism is screwed into an opening 46. The pipe 47 connectswith a chamber 55, Fig. 3, in a casing 56 on which is bolted a second casing 58, a pressure-responsive diaphragm 60 being clamped between the casings. When the pilot valve opens, water passes to the chamber 55, and thence, by a strainer 71 and restricted opening 72, to a chamber 66. If the pilot valve immediately re-closes, as after water-hammer, the water drains away through a still smaller opening 74 and chamber 76. If the pilot valve remains open, as when a sprinkler head has opened, most of the water from chamber 66 passes by a passage 67 to the casing 58. building up pressure above the diaphragm 60. The latter is connected by a stem 90, Fig. 1, to a valve 82 in a chamber 78 which is connected by a pipe 87 to the main water pipe 10. When the pressure in chamber 60 is sufficient to overcome that in the chamber 78, the valve 82 is opened, and water from the main is free to pass to a chamber 79 and thence by a pipe 93 to the alarm mechanism. The pipe 93 leads to a water wheel 106, Fig. 2, which drives, by means of a shaft 107, a wheel 99 carrying centrifugal elements 100 adapted to strike a gong 97. In addition to this alarm, or as an alternative, water from the pipe 93 may pass to a casing 118, Fig. 1, containing a diaphragm 119 adapted to move a switch 110 to close an electric circuit containing a bell and a lamp. A cover 69 in the casing 56 gives access to the members containing the apertures 72. 74 so that these may be replaced by members having apertures of different sizes, so as to vary the degree of retardation. The pipes 47 and 87 are provided with stop cocks, so that the alarm mechanism may be rendered inoperative without putting the sprinkler out of action.

Title: Apparatus for connecting a pipeline with a selected branch line
IPC: E21B23/12
Filed: 1971-10-09
Abstract: 1376942 Pneumatic conveyers CAMERON IRON WORKS Inc 9 Oct 1971 [8 March 1971] 32420/71 Heading B8A [Also in Division F2] Articles moving along a duct under fluid pressure, e.g. tools being conveyed between well-heads, are diverted by switches into branch ducts appropriate to their destination by interaction between the article and the switch which causes the switch to rotate to be aligned with said branch duct. The switch comprises a first part 23A coupled to the duct 21 and having a left handed spiral groove 56 in the bore 31 thereof and a second part 23B formed of two portions 29A, 29B fixed together for rotation within a housing, the first portion having a right handed spiral groove 55 and the second portion comprising a curved duct 37 to connect the bore 34 of the first portion 29A with a respective one of the branch ducts 21A-21D. The tool 50 is formed of two portions 51, 52 coupled together by a universal joint 50A and each having a key 53, 54 urged by springs (58), Fig. 7 (not shown), outwardly of the respective tool. The key 53 of the first portion 51 is angled to engage the spiral groove 55 and the key 54 of the second portion 52 is angled to engage the spiral groove 56. The latter being fixed causes the tool to rotate and thus causes the second part 23B of the switch to rotate to align the duct 37 with the appropriate outlet. The first portion 51 of the tool is adjustably rotatable relative to the second portion 52 of the tool by means of a pin (65), Fig. 5 (not shown) co-operating with appropriate apertures (66) in the coupling 50A, to determine the extent of the rotation of the second part 23B of the switch and thus its alignment with the appropriate outlet. In a further embodiment, Figs. 8, 13, 16 (not shown), the pipe-line (70) has a series of switches (72A), (72B), (72C) each with only one branch (71A), (71B), (71C) the angle of the groove 86 in the second part (82B) of the switch being different for each switch and the leading part (75B) of the tooling being chosen with a key (87) angled to correspond with the angle of the groove of the switch at which it should be deflected into a branch line. The groove (86) in the second part (82B) of each switch has lead-in portions (86B), (86C) at each end thereof to allow the movement of the tool in the reverse direction and in so doing to rotate the switch to its original position.

Title: Improvements in and relating to rotary pumps
IPC: F25B31/02
Filed: 1952-12-22
Abstract: 777,322. Rotary pumps. GENERAL ELECTRIC CO. Dec. 22, 1952 [Dec. 27, 1951], No. 32440/52. Class 110 (2). A rotary compressor 3 is housed in the sealed case 2 of a refrigerating unit 1. The compressor has an upper container part 4 spaced from a lower part 5 by an annulus 6 coaxial with a vertical shaft 9 driven by a motor (not shown) housed in the case 2. On the shaft 9 and aligned with the annulus 6 is an eccentric 10 on which a rotor 11 is mounted for rotation with the shaft. A slidable abutment 17 having its outer end in a recess 18 of the compressor casing extends through a radial slot 12 between an intake port 13 and an exhaust port 14. A spring 20 holds the abutment against the rotor. A mixture of refrigerant and lubricating oil drawn in through a suction line 15 and exhausted through port 14 passes into an annular chamber 16, whence the mixture is led by a conduit 23. To supply oil to the shaft and rotor for lubricating purposes and to equalize the pressure on both sides of the eccentric a branch conduit 24 leads part of the mixture to a groove 26 in the shaft 9, thence through a passage 27 in the eccentric to a groove 28 in the shaft. Any of the mixture reaching the top of the container 4 passes into a reservoir 29 where the gas separates out and passes through passages 31 into the case 2 and returns thence to the refrigerating system through exhaust line 32. Oil from the reservoir 29 passes through a passage 33 to the radial slot 12 to form a seal. The main flow through the conduit 23 passes to an annular chamber 34 of the compressor where oil is deposited over the surfaces of the abutment 17. As the abutment is reciprocated some of the oil and gas mixture passes into the case 2 through the recess 18 leaving an oil film sealing the edges of the recess. On stopping the compressor, pressure in the case 2 is higher than in the suction line 15. The oil. seals are therefore blown into the intake port 13 and the pressures equalized. On restarting the unit there is insufficient oil in the slot 12 and recess 18 to seal the compressor and only after several revolutions is the abutment sealed and the compressor again loaded.

Title: Improvements in fuel element arrangements for nuclear reactors
IPC: G21C1/07
Filed: 1961-09-12
Abstract: 935,130. Nuclear reactors. A. P. PEDRICK. Sept. 12, 1961, No. 32600/61. Class 39 (4). A nuclear reactor in which fuel elements are arranged in columns, one above the other, in vertical tubes through which coolant flows, the tubes having constrictions in the bores to produce variations in the coolant flow rate to sustain the fuel elements in fluid suspension. The fuel element consists of a fissile material within a casing of magnesium, aluminium or any other low neutron absorbent material which may be dimpled to increase its surface area. The ele - ments may be disposed (Fig. 3) within a flow tube I provided with necks H which cause a local increase in the flow of the medium E so maintaining the element in fixed position. Also the spheres may be prevented from being blown out of the tube by making the top of it conical as at J. Similarly a reduced diameter K prevents the spheres dropping out. The elements are passed into the reactor (Fig. 5) through a central hole P to a distributer device M which feeds the elements to parallel flow tubes I arranged in rings, the axes of which are parallel to the vessel L. The fluid which maintains the elements in fluid suspension, enters through the holes R and leaves through the holes S. To empty the flow tube of fuel elements a heavy sphere is passed into the tube which causes the elements to drop through the hole Q. The fuel elements may be placed in a spherical casing (Fig. 2, not shown) having perforations which allow a fluid to pass through to cool the elements. The perforated casing may then be placed in fluid suspension in the core of the reactor. Specifications 756,014 and 812,809 are referred to.

Filed: 1922-11-29
Abstract: 206,384. Beatty, W. G. Nov. 29, 1922. Rope grips.-Relates to the detent and tripping mechanism of an overhead trolly a of the kind in which parallel jaws r, r<1> for gripping the hoisting and hauling rope are actuated by an oscillating locking-member h. The rope is anchored to a crank g<1> on the spindle g of the member h, so that the weight of the load' pulls the member h towards the left. The member h is connected with the rope grip by a link t, and in moving to the left closes the grip. In the position shown the member h is held in the right-hand position, with the ropa grip released, by a detent j, which is provided with lugs bearing against the shoulders h', Fig 6. When the load is raised up to the trolly a, a tripping-lever k' pivoted at l is engaged and raised so as to lift the detent in guides in the trolly, releasing the member h and closing the rope grip for traversing. When the trolly is run back again, the member l engages a stop-block p<1> on the track and is moved over to the right, releasing the rope grip and allowing the detent j to drop into the locking position. The detent may also be operated by a hand-rope s.

Title: Improvements in prepayment meter machanism
IPC: G07F15/00
Filed: 1932-11-18
Abstract: 410,212. Prepayment mechanism for meters. CONNOR, R., Tame Side Works, Dobcross, near Oldham, and MEASUREMENT, Ltd., Terminal House, Lower Belgrave Street, London. Nov. 18, 1932, No. 32706. [Class 27.] In prepayment meters having epicyclic quantity mechanism, means are provided whereby, should the switch fail to open or the valve to close, when the amount of prepaid commodity has been supplied, further delivery of commodity through the meter will cause the metering mechanism to be completely disconnected from the prepayment mechanism so that false indications of the extent of prepayment are prevented. As applied to an electricity meter, the planet carrier p, Fig. 2, of the epicyclic mechanism is driven in opposite directions by the coin mechanism and the meter respectively and rotates a cam disc q, Fig. 4, having two notches r, s. The notch s cooperates with a pin t<1> on a trip catch t which releases a switch arm z and allows the switch to open when the pin t<1> enters the notch, which occurs just before a pin 8 on one arm of a threearmed lever 9 enters the notch r. Should the switch fail to open, continued rotation of the disc q allows the pin 8 to enter the notch and the lever 9 to be rocked on its pivot. This withdraws the vertical arm of the lever 9 from a position at the end of a spindle 10 in which it normally prevents endwise movement of the spindle under the action of a spring 11. The spindle carries two wheels j, k in the driving train between the meter and the epicyclic mechanism which wheels are thus moved to the dotted line position, Fig. 2, to disconnect the meter from the differential gear.

Abstract: 537,275. Ester products ; making emulsions ; food preparations ; anti-adhesion materials for use in cooking and baking. SCHOU, H. Dec. 22, 1939, No. 32734. [Class 2 (iii)] [Also in Groups III and VI] Products having dispersing properties useful in the manufacture of stable emulsions of the water in oil type are obtained by heating a fatty acid ester of a polyhydroxy compound having at least one unesterified hydroxy group in the alcoholic residue with a polymerized and/or oxidized drying or semi-drying fatty acid triglyceride. In modifications (a) an unpolymerised and/or unoxidized triglyceride is used and the polymerization and/or oxidation is effected as a separate step, and (b) a mixture of polyhydroxy compound and free fatty acid and/or ester replaces the hydroxy containing fatty acid ester. In examples : (1) a polyglycerol ester of palmitic acid is heated in an atmosphere of carbon dioxide or nitrogen under reduced pressure with soya bean oil which has been blown with air until gelatinization has set in; the product may be used as dispersing, stabilizing and water-binding agent in the manufacture of margarine with acidified skim milk as the disperse phase and an oil-fat mixture as the continuous phase ; (2) polymerized soya bean oil is heated with a mixed acetic acid, stearic acid polyglycerol ester containing hydroxy groups ; the product is used for making a dispersion of water in peanut oil suitable for greasing forms and plates used in baking bread ; (3) the product of the previous example is oxidized with air and used for making a dispersion of water in a mixture of coconut oil and hydrogenated whale oil; (4) gelatinized soya bean oil is heated in an atmosphere of carbon dioxide with a mixture of glycerol, stearic acid and a small amount of sodium acetate as catalyst; soya bean oil may be replaced by linseed, sunflower, cotton seed, wood or whale oil, and diluents such as lard, tallow and hydrogenated cotton seed or whale oil may be used. The hydroxy-containing esters may be derived from formic, propionic, oleic, arachic or linoleic acid and polyhydroxy compounds such as glycol, mannitol, sorbitol or mono-, di- or poly-saccharides. The products may be used in association with other dispersing or stabilizing agents such as lecithin, mono- or diglycerides of higher fatty acids, polymerized and/or oxidized oils and/or fats and saccharides. They may also be used with edible oils in the manufacture of creaming agents. Reference is made to dispersions of water or aqueous liquids in fatty acid triglycerides, hydrocarbons and waxes and to the manufacture of margarine, shortenings and greasing emulsions which are stable to heat and pressure.
